In a posting to the Hula mailing list, Novell has stated that it is no longer providing full-time developers to work on Hula. Hula was unleashed in February 2005 to much fanfare. Things seem to have been quite recently, despite the news that iFolder and Hula would be combined into something called Maui.

Much of what Novell was promising for Hula was ideas that have been either implemented or planned in the Citadel project [http://www.citadel.org] anyway. (We pitched Citadel to them about six months before the Hula announcement ... and they said they weren't interested, and then they announced their project. Draw your own conclusions.)

Anyway, do try Citadel -- it is a very well-integrated collaboration server with an ajax-style web user interface, built-in data stores, lightweight implementations of all relevant protocols (POP, IMAP, SMTP, etc.) ... very easy to install, and just a joy to use.
